Embedded elastic dampening material

There also exists an embedded elastic dampening material in the blades, which minimizes vibrations to improve resiliency. Because the blade is lighter and experiences lower centrifugal force further enhanced the blade s durability occurs. Small-scale wind tunnel tests show they last 10 to 15 times longer than any existing blade. The No. 1 maintenance task is the constant process of taking engines apart to check the blades.
